I paused the campaign at 3:43 PM yesterday. According to my stats I only received 25 impressions yesterday 0 clicks. Today I checked my account and have been charged for over 3000 impressions that supposedly happened today, BUT my campaign had been paused for more than 17 hours!!! Not to mention I was charged $4 over my daily budget. I have contacted Google but don't expect to hear back for a couple of days. Anyone have this happen?

After the resident AdWords Pro at DigitalPoint Forums, GuyFromChicago, drilled him with questions, he got a response from Google that read:

Thank you for your email. I'm sorry to hear that you've had trouble with your Google AdWords campaign. I understand your paused campaigns are accruing clicks and impressions. Our engineers are currently working to solve the problem and hope to reach a resolution shortly. We appreciate you for your patience.

Once this issue has been resolved by the engineers, please be assured that any applicable credits will be automatically processed.

So it seems to be a bug in Google. So you as an advertiser should be aware of this. Make sure you aren't being charged as well.

I suspect Google will refund the advertiser for the impressions and clicks he accrued.
